使用Android模拟器“-scale”选项的有损图片

我有启动模拟器的问题，比例选项介于0.4和1之间，不包括 .

$ emulator -avd avd10 -verbose -scale 0.8

而模拟器看起来像http://img225.imageshack.us/i/avdm.png/

它似乎工作（我可以解锁屏幕，调用菜单等），但由于有损的图片它不可用 . 使用其他比例选项，不在0.4和1之间，它看起来很好 .

技术信息：
Android的sdk_r12
X.Org X Server 1.10.2

$ uname -a Linux笔记本电脑2.6.39-ARCH＃1 SMP PREEMPT Mon Jun 27 21:26:22 CEST 2011 x86_64 Intel（R）Core（TM）2 Duo CPU P8600 @ 2.40GHz GenuineIntel GNU / Linux

仿真器输出是相同的，带有scale选项，没有它 .
